Process Control TechnologyModel: PCT-100

GENERAL DESCRIPTION

The PCT-100 Process Control Technology unitrepresents a system typically found in the processindustry.

The PCT-100 consists of Process Units ControlModule with Power Supply, together with acomprehensive interactive control program. Thesoftware has been developed to act as an inclusive PIDteaching tool and provides historical data trendingfeatures.

The Control Module contains signal conditioning andconnections to allow both PC and PLC control. Thereare also connections provided to allow connection to aPID controller. The control module also contains adiagram of the process.

Exercises for the PCT-100 begin with setting up andexecuting a process cycle, through to optimising thePID controllers by estimating P, PI and PID parametersusing Ziegler Nichols process reaction curve orultimate cycle methods. Formulation of problems andresulting solutions coupled with bench-marking aremanifest through tutorials.

Liquid contained in a Sump Tank is pumped aroundthe process unit to a Process Tank where it can beheated. The flow rate and the heat input can be

controlled manually, or via a PC, a PLC or a PIDcontroller.

PT100 temperature sensors are used to determine thetemperature of the liquid in the Sump Tank and theProcess, and a radiator with forced air cooling.In addition to supplying this data to the controller, it isalso displayed on LCD displays. An impeller type flowmeter is used to determine the flow rate, the data fromwhich is supplied both to the controller and also to anLCD display.

Transducers are used to detect the water level and for pressure measurement within the process tank. Liquidlevel measurement is achieved using a magnetostrictivesensor.

The liquid in the process tank can be heated using a400W heating element. The power being input fromthe heater is shown on an LCD display.

The PCT-100 allows the investigation of:• Control of discrete processes• PID control• Temperature, Level, Pressure and Flow control• Graphical Monitoring of real time processes.
